Extract, inflate, and beautify embedded code

Recover a Base64-wrapped raw-DEFLATE code fragment from surrounding text and format it for review.

Install in Serialize

What it can do

Isolate a long Base64 value
Recover raw-DEFLATE bytes
Format compact code for static review

How the recipe works

Regular expression

Extract the encoded token and discard surrounding prose.

From Base64

Decode the printable transport wrapper.

Raw Inflate

Inflate the headerless DEFLATE stream.

Generic Code Beautify

Add readable whitespace and indentation.

Demonstration

Sample input

telemetry payload: S87PKy5RKEotyC8qsa0uLkksKS22UsrPVtIpLcoptopWyigpKSi20tdPyU8u1kutSMwtyEnVK0ktLtFPVIqttQYA; end

Expected result

const report = {

When to use it

Alert triage
Packed configuration exercises
Inspecting compressed script fragments

Adapt it

Swap Raw Inflate for Gunzip or Zlib Inflate when the decoded header identifies a different compression wrapper.
